Bicycle and car production since 1950
1950年来的自行车和汽车产量

FAT-BUSTING but not wallet-busting, the humble bicycle is an increasingly popular choice of transport. Around 130m bikes rolled off production lines in 2007 and even more are set to be made this year. Bicycle and car production grew pretty much in tandem in the two decades beginning in 1950. But since 1970 bike production has nearly quadrupled while car production has roughly doubled. Much of the recent growth has been driven by electric bikes; production has doubled since 2004, to 21m.
由于能减肥却不需花大价钱，不起眼的自行车正日益成为一种流行的供人选择的交通工具。2007年约有1.3亿辆自 行车出产，今年的产量则会更大。自1950年到1970年的20年间，自行车和汽车产量均有较大增长。但自1970年以来，自行车产量翻了两番，而汽车产 量不过约是原来的2倍。最近自行车产量的增长主要是由于电动自行车的推动。2004年以来电动自行车产量已翻了一番，达到了2100万辆。
